-QUlLL-W|NDING MACHINE.

Specification of Letters Patent.

To ctZZ whom it may concern:

Be it known that I, EDWARD BRADLEY,

a citizen of the United States, and a resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Quill-W'inding Machines, of which the following is a specification.

My invention relates to a quill-winding machine, with the Object in View of providing means for promptly arresting the rotary movement of the quill when the winding of the thread thel'eon is completed, means for maintaining the quill-spindle in parallelism with the rod on which the guide feed-roller travels, means for regulating the-size of the quill, and certain features of structure and combinations of parts by which the aforesaid Objects are practically Obtained.

A practical embodiment of my invention is re 'iresented in the accompanying drawings, in which Figure 1 is a view in side elevation of a part of a quill-winding machine. Fig. 2 is an end view of the same. Fig. 3 is a transverse section in the plane of the line A A of Fig. 1. Fig. 4 is an enlarged top plan view of one of the spindles and the mechanism which immediately cooperates therewith. Fig. 5 is a view of the same in side elevation. Fig. 6 is a view of the same in reverse side elevation. Fig. 7 is a vertical longitudinal section of the same. Fig. 8 is a view of the same in end elevation. Fig. 9 is a transverse section in the plane of the line B B of Fig. 4, and Fig. 10 is a transverse section in the plane of the line C C of Fig. 4.

The machine which I have chosen to illustratc my invention is one in which the reciprocating rods for producing the traverse motion are simultaneously driven by a cam from the head of the machine. My present invention, however, applies equally wellv to a machine in which the reciprocating rod is independently dtiven at each spindlefor instance, by the gear mechanism shown, described, and claimed in my companion ap plication entitled Guide motion for quillwinding machines, Serial N 0. 337,135, filed of even date herewith.

The head-frame of the machine is denoted by 1, and the spindles, with their accompanying parts, are arranged in horizontal series 011 supporting-rails 2 and 3, extending from the head-frame 1 to the foot-frame, (not shown) Patented April 16, 1907.

' the front and back of the frame by means of.'

as is usual. Power is applied to a drive-pub ley 4 from a suitable source, (not shown,).

and from a part of the pulley 4 a belt 5 leads to the several spindles for imparting to them their rotary motion, the arrangement in the present instance being such that the belt passes under the driving-pulleys on a series.

of spindles extending in one (.lirection from the frame and Over the driving-pulleys from the series of spindles extending in the opposite direction fzomthe frame, as clearly shown in Fig. 3. 'I he pinion 7, fixed to rotate -with the pulley 4, engages a spur-wheel 8, on

which there is an annular cam 9, which byengaging a swinging arm 10, connected by a link 11. with an arm 12, rocks the-traverseshaft 13, carrying a traverse-arm 14 for each spindle, and also an arm 15, which is Connected by a link 16 with an operating-arm 17 on the traverse-shaft 18 for the oppesite series of spindles, the latter shaft 18 being provided with each spindle.

a t'rave:searm 19, one for The shafts 13 and 18 are rocked in one direction by springs 20 and21,

respectively. Up to this point the niechan-Z ism is of well-knOwnform.

Referring now to Figs. 4 to 10, inclusive,

each spindle consists of a front section 22 and a rear section 23.

These two spindle sections" are mounted in the spindle-frame 24 to-ro tate independentlyof each other when un locked and to rotate as one when locked! The rear section 23 carries the belt-pulley? 25, which is at all times in Contact with the belt 5 and is constantly driven while the frontsection 22 to which the quill'is attached isinl termittently driven depending uponwhetheriif f: it is locked to or released from the rea'rjsec- 95 sliding clutch member 26, which may be slid tion 23. The front section 22 has thereon a into and out of engagement with a clutch member 27, fixed to the-rear section 23 0f the spindle. be conveniently engaged with the spindlesection 22 by means of the ordinary feather- The sliding clutch member 26 may 1 i go and-groove connection, the feather being shown at 28. ated by a shifting-ar1n29, fixed to a longitudinally-reciprocating rod or bar 30, which is under spring tension by means of a spring 31 The clutch member 26 is opera tending to slide the bar in a direction to re lease the clutch member 26 from the clutch member 27. The rod 30 is provided with a handpiece 32 on its end for pushing the rod, and hence the clutch member 26, into locking engagement by hand, and the handpiece 32 is provided on its side (see Fig. with a lug 33 in position to be engaged by a latch 34, constructed to rock on a pivot 35, together with the trip-arm 36. The latch 34'and arm 36 are'under spring tension by means of a spring 37, tending to throw the latch 34 into position to catch over the edge of the lug 33 4 and hold the clutch-operating rod in position to lock the clutch members. The triparm 36 extends upwardly into the path of a stop 38, fixed on a rod 39, which in the present instance is provided with a guide-eye 40 and is made to reciprocate together with the traverse mechanism.

The guide feed-roller is denoted by 41 and is loosely mounted on the reciprocating rod 42, which is operated by the traversearm such, for example, as the arm 14 shown in Fig. 3. This rod 42 slides and rocks in bearings 43 44 on the spindle-frame, while its outwardly-extended portion (denoted by 45) is screw-threaded and offset from the part of the rod which rests in the bearings 43 44i. 0., the axis of the screw-threaded part 45 of the rod 42 is eccentric to the axis of the inner part of the rod. This offset is clearly shown in Fig. 4, and its object is to bring the guide feed-roller 41 bodily nearer to or farther away from the axis of the quill-holder or spindle by rocking the. rod in its bearings 43 44 and retaining it in such rocked positionfor example, by means of a collar 46, through which a set-screw 47 projects into engagement with the part 45 of the rod and from which an arm 48 extends upwardly and partially embraces the rod 39.

By loosening the screw 47 and rocking'the rod 42 the screw-threaded portion may be adjusted with a great degree of accuracy nearer to or farther away from the spindle without interfering with the reciprocatory movement of the ro The hub of the guide feed-roller 41 is connected, by means of a bifurcated arm 49, with the rod 39, to which the arm 49 may be secured by means of a set-screw 50. The bifurcated arm 49 engages a groove in the hub of the guide feed-roller 41, so as to permit the latter to rotate, while at the same time being carried bodily back and forth with the rods 42 and 39.

The guide feed-roller 41 is caused to travel along the screw-threaded portion 45 of the rod 42 by means of a latch 51, in the present instance a latch formed of a strip of spring metal fixed'at one end to the hub of the roller 41 and extending thence upwardly in curved the groove between two consecutive threads of the screw. It may be thrown out of engagement with the screw by tilting it back, as shown in dotted lines but when allowed to assume its normal position (shown in full lines) it causes the roller 41 when rotated on the screw 45 to travel bodily along the said screw-threaded portion.

The support for the front section of the spindle (denoted by 52) is hinged to the spindle-frame at 53, so as to permit the front section of the spindle to be tilted outwardly and inwardly away from and toward the guide feed-roller 41.

It is of great importance that the axis of the spindle be kept at all time in parallelism with the axis of the reciprocating rod 42, and in order to take up any wear which may have thrown it out of parallelism and to adjust it in any instance accurately to such parallelism I provide a screw 54, which ongages a screw-threaded hole in the lug 55, uprising from the frame 52 and rests in a socket formed in a part 56 of the stationary spindle-frame. A lock-nut 57 serves to hold the screw in its adjustment while a torsionspring 58 on the pintle of the swinging frame 52 serves to hold the spindle swung inwardly toward the roller 41 or reciprocating rod 42 as far as the adjusting-screw 54 will permit it.

The handpiece 32 is further provided with a pair of lugs 59 60, (see Figs. 8 and 9,) which engage the opposite sides of a tongue or rib 61, depending from the under side of the swinging frame 52 and set oblique to the axis of the spindle-section 22, so that as the trip-lever releases the handpiece and rod 30 the outward movement of the said handpiece under the tension of the spring 31 will crowd the swinging frame 52, carrying the part 22, of the spindle outwardly against the tension of its torsion-spring, thereby setting the quill-carrying portion of the spindle obliquely outward from the roller 41 and in a convenient position for removing the quill from the spindle. When the handpiece is pushed inwardly to force the clutchsections into engagement, the swinging frame carrying the quill-holding part of the spindle will be swung back into alinement. It is further to be not-ed that when the sliding clutch member 26 is released from the driving member 23 it will be thrown by the spring 31 into frictional engagement with the spindlesupport 52, and the rotation of the quill-carrying section of the spindle will be promptly stopped, this frictional engagement of the sliding section 26 with the support 52 serving as a brake.

In operation the guide-roller 41 as it is bodily reciprocated by means of the traverse mechanism will come at each return form, as shown, and then folded back on itself 1 movement into engagement with the thread and projected down into position to engage l on the quill and will be given more or less of a rotary movement, which will gradually feed it outwardly, and it wiltcarry along with it the rod 39, on which the stop 38 is located for engaging the trip-arm 36. The moment when the stop 38 shall engage the trip-arm is determined by the position in which the stop 38 is located on the.arm 39. When the winding 01' the quill is completed, the stop 38 will have been moved outwardly by the action of the roller 41 into a position where it will engage the trip-arm 36 and permit the rod 30 to spring outwardly, carrying with it the clutch member 26, releasing the quill-carrying section of the .spindle from the driving-section, and will promptly stop its rotation, as hereinabove explained. When a new quill has been placed in position, the sliding member 26 of the clutch may be slid back into engagement with the rotating member by pushing on the handpiece 32, and in this position it will be locked by the latch 34 until it is again released either by the operation of the gradually-increasing amount of thread on the spindle or by hand by simply operating the trip 36,1f occasion requires such action.

VVh'at I claim is 1. A quilling-spindle composed of a front section and a back section and means for swinging the front section at an angle to the back section.

2. A quilling-spindle comprising a front section and back section, means for locking the front section to and releasing it from the back section and means for swinging the front section at an angle to the back section.

3. A quilling-spindle comprising a front section and back section and a hinged sup port for the front-seetion bearing for swinging the lront section at an angle to the back section.

4. The combination with the reciprocating rod for carrying the guide feed-roller of the quilling-spindle, of a spindle for receiving the quill and means for adjusting the quillcarrying spindle into parallelism with the reciprocating rod.

5. The combination with a quilling-spindle and means for operating it, of a'reciprocating rod for guiding the thread, the said rod having two parts one part formed eccentric to the other part, a guide feed-roller mounted on the reciprocating rod and means for holding the rod in different rocked positions to vary the distance of the roller from the spindle.

6. The combination with a reciprocating rod having two parts the outer part being eccentric to the inner part, 'a guide ieedroller thereon and a quill-carrying spindle mounted in relation thereto, of a reciproeating rod provided with a-guide for directing the thread to the quill and an arm ongaged with the said reciprocating arm and with the thread-guide rod for-holding the reciprocating rod in different rotary adjust ments.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 17th day of September, 1906.
